We don't watch the world cup because of the African teams. That's not a factor. In fact, we don't even consider that African Arabic teams to be African. We watch because it is football and the best of the best will be playing. Just the same way we don't follow the English Premier league because of the African players, if there's one - we'll and good.
If African teams don't make it to the quarters it will be because they did not deserve to and that's good for the game.
On another note, I hope Russia is not eliminated in the first round, that would be painful even for me and I'm not even a fan of Russia.
BBI will solve it :)
